一：下载Elasticsearch安装包并解压
二：进入解压后的elasticsearch目录：
1：新建data目录：mkdir data
2：修改config/elasticsearch.yml
三：后台启动：./bin/elasticsearch -d
Elasticsearch集群用配置文件关联：以三台为例；配置集群只需要更改配置文件中：节点名称，ip地址两个参数
# 注：Elasticserch7.0开始，当一半以上的候选主节点永久丢失，集群将不会自动恢复。 # 在添加或删除节点时，Elasticsearch会自动的通过更新集群的投票配置（voting configuration）来维持最佳的容错级别。 #voting configuration是一组当前可以参与投票的的候选主节点。通常，voting configurations包含集群中所有符合条件的候选主节点。 #所有集群状态的更新都需要有voting configurations中一半以上的节点同意。 # 集群名称 cluster.name: ****** # 节点名称 node.name: node-a-1 # 网络连接地址 network.host: -----ip------- # 端口 http.port: 9500 # 跨域访问，elasticsearch-head提供检测 http.cors.enabled: true http.cors.allow-origin: "*" http.max_content_length: 200mb #集群通信端口 transport.tcp.port: 9400 #不运行Macos下的es（内部应该有运行xpack） xpack.ml.enabled: false #集群中主节点最少设置3个及以上 # 是否设置主节点,默认为true node.master: true # 是否允许节点存储数据,默认为true node.data: true # 为了避免脑裂，集群节点数最少为 半数（N/2）+1 discovery.zen.minimum_master_nodes: 2 # 7.x版本后，需要注意(cluster.initial_master_nodes，discovery.seed_hosts) # 从7.0版本开始，如果要启动在多个物理主机上启动一个全新的集群，必须指定参与第一次投票选举的候选主节点。这个过程称为集群启动引导，仅在集群第一次启动时才需要。 # cluster.initial_master_nodes 参数设置一系列符合主节点条件的节点的主机名或IP地址来引导启动集群。 # 注：如果不是候选主节点，则不需要配置此项 cluster.initial_master_nodes: ["node-a-1", "node-a-2", "node-a-3"] #发现子系统的相关配置以便节点可以互相发现 #自动发现设置，配置之后集群的主机之间可以自动发现 discovery.seed_hosts: ["172.16.70.195:9400", "172.16.70.196:9401", "172.16.70.200:9402"] #基于文件的自动发现设置，配置之后集群的主机之间可以自动发现。 #discovery.seed_providers对应旧版中的discovery.zen.hosts_provider #discovery.seed_providers: 文件 #一旦你点击3个节点,倒计时时钟开始,然后集群将在5分钟内恢复(默认值)或者如果你点击5个节点.基本上它允许您设置最小阈值(recovery_after_nodes), #并使用超时(recovery_after_time)等待所需的状态(expected_nodes).命中recovery_after_nodes后,或者当命中expected_nodes(无需额外等待)时, #您将恢复recovery_after_time – 以先到者为准. gateway.recover_after_nodes: 3 gateway.expected_nodes: 5 # 网络参数配置 network.tcp.keep_alive: true network.tcp.no_delay: true #设置是否压缩tcp传输时的数据，默认为false，不压缩。 transport.tcp.compress: true #集群内同时启动的数据任务个数，默认是2个 cluster.routing.allocation.cluster_concurrent_rebalance: 16 #添加或删除节点及负载均衡时并发恢复的线程个数，默认4个 cluster.routing.allocation.node_concurrent_recoveries: 16 #初始化数据恢复时，并发恢复线程的个数，默认4个 cluster.routing.allocation.node_initial_primaries_recoveries: 16 # 索引数据存放的位置 path.data: /opt/cmh/elasticsearch/data # 日志文件存放的位置 path.logs: /opt/cmh/elasticsearch/logs

# ======================== Elasticsearch Configuration ========================= # # NOTE: Elasticsearch comes with reasonable defaults for most settings. # Before you set out to tweak and tune the configuration, make sure you # understand what are you trying to accomplish and the consequences. # # The primary way of configuring a node is via this file. This template lists # the most important settings you may want to configure for a production cluster. # # Please consult the documentation for further information on configuration options: # https://www.elastic.co/guide/en/elasticsearch/reference/index.html # # ---------------------------------- Cluster ----------------------------------- # # Use a descriptive name for your cluster: # #cluster.name: my-application # # ------------------------------------ Node ------------------------------------ # # Use a descriptive name for the node: # #node.name: node-1 node.name: node-1 # # Add custom attributes to the node: # #node.attr.rack: r1 # # ----------------------------------- Paths ------------------------------------ # # Path to directory where to store the data (separate multiple locations by comma): # path.data: /newdisk/es7/dbdata # # Path to log files: # path.logs: /newdisk/es7/dblogs # # ----------------------------------- Memory ----------------------------------- # # Lock the memory on startup: # #bootstrap.memory_lock: true # # Make sure that the heap size is set to about half the memory available # on the system and that the owner of the process is allowed to use this # limit. # # Elasticsearch performs poorly when the system is swapping the memory. # # ---------------------------------- Network ----------------------------------- # # Set the bind address to a specific IP (IPv4 or IPv6): # #network.host: 192.168.0.1 network.host: 0.0.0.0 network.publish_host: 120.120.120.120//这里是你的服务器IP # # Set a custom port for HTTP: # http.port: 9200 # # For more information, consult the network module documentation. # # --------------------------------- Discovery ---------------------------------- # # Pass an initial list of hosts to perform discovery when this node is started: # The default list of hosts is ["127.0.0.1", "[::1]"] # #discovery.seed_hosts: ["host1", "host2"] # # Bootstrap the cluster using an initial set of master-eligible nodes: # node.master: true node.data: true #cluster.initial_master_nodes: ["node-1", "node-2"] cluster.initial_master_nodes: ["node-1"] # # For more information, consult the discovery and cluster formation module documentation. # # ---------------------------------- Gateway ----------------------------------- # # Block initial recovery after a full cluster restart until N nodes are started: # #gateway.recover_after_nodes: 3 # # For more information, consult the gateway module documentation. # # ---------------------------------- Various ----------------------------------- # # Require explicit names when deleting indices: # #action.destructive_requires_name: true http.cors.enabled: true http.cors.allow-origin: "*"
